Hi, Here are the results of comparison of kernel 2.5.55 and 2.5.54 on TIObench. key findings are listed in the table. Values in the table indicate approximate percentage change with respect to previous result. Please see the mail in full window to see the formatted results.
------------------------------------------------------------- test 2.5.55 (as compared to 2.5.54) APPROXIMATE % change ------------------------------------------------------------- rate (megabytes per second) no much change CPU % utilization 15% decrease Average Latency 15% decrease Maximum latency less than 10 % increase CPU efficiency 10% increase -------------------------------------------------------------
No size specified, using 252 MB
Unit information ================ File size = megabytes Blk Size = bytes Rate = megabytes per second CPU% = percentage of CPU used during the test Latency = milliseconds Lat% = percent of requests that took longer than X seconds CPU Eff = Rate divided by CPU% - throughput per cpu load
